Formula for Mitered Quilt Borders?

For example, let's say our quilt top is 40” x 50” and the borders are 2″ wide. The equation for the top and bottom border would be 40″ + 4″ + 6″ = 50″, so those two borders would each measure 2″ x 50″. The equation for the side borders would be 50″ + 4″ + 6″ = 60″, so my our side borders would measure 2″ x 60″.
